2-Benzyloxypyrimidine derivatives of the formula (I) shown in Table 1 (1/15 to 15/15) can be synthesized in accordance with the following scheme: ##STR9##

As shown in the above Reaction scheme I, the compound of the formula (I) may be produced by reacting the compound of the formula (II) with a substantially equal molar amount of the compound of the formula (III) in the presence of a basic compound, preferably in a solvent such as amides (e.g., dimethylformamide, dimethylacetamide, and N-methyl-2-pyrrolidinone), ethers (e.g., diethyl ether, dimethoxyethane, diisopropyl ether, tetrahydrofuran, diglyme, and dioxane), and aromatic hydrocarbons (e.g., benzene, toluene, xylene, and methylnaphthalene), preferably at a temperature in the range of -20° C. to 150° C. for a period of about 0.5 hour to one night (about 12 hours).

An iodide such as sodium iodide and potassium iodide or a crown ether such as 18-crown-6 and dibenzo-18-crown-6 may be added to the reaction as a reaction accelerator.

Examples of the compounds (II) which can be used for the production of the compounds (I) are shown in Table 2.

The compounds of the formula (III) which may be used as starting materials in the Reaction scheme I can be either commercially available or easily synthesized.

As those in which Z represents a halogen among substituted pyrimidine derivatives of the formula (III) to be used as starting materials in the Reaction scheme I, commercially available reagents such as 2-chloropyrimidine, 2,4-dichloro-6-methylpyrimidine, and 2,4,6-trichloropyrimidine may be used. Alternatively, they may be synthesized by the process described in J. Chem. Soc. (C), 2031, (1966).

Among substituted pyrimidine derivatives of the formula (III), those of the formula (III-e) in which Z is linked to the pyrimidine ring through the sulfonyl thereof can be synthesized by oxidizing sulfur of 2-(alkylthio, aralkylthio, or arylthio)pyrimidine derivatives of the formula (IV-e), as shown in Reaction scheme II: ##STR10## wherein R¹ and R² each independently represents hydrogen, a halogen, hydroxyl, C₁ -C₄ alkyl, C₁ -C₄ haloalkyl, C3-C₅ alkenyl, C₃ -C₅ alkynyl, C₁ -C₄ alkoxy, C₁ -C₄ haloalkoxy, C₃ -C₅ alkenyloxy, C₃ -C₅ alkynyloxy, C₁ -C₄ alkylthio, or phenyl;

Z¹ e represents C₁ -C₄ alkylthio, C₇ -C₉ aralkylthio, or arylthio (usually C₆ -C₈); and

Ze represents C₁ -C₄ alkylsulfonyl, C₇ -C₉ aralkylsulfonyl or arylsulfonyl (usually C₆ -C₈).

Ze preferably includes the following groups:

C₁ -C₄ alkylsulfonyl such as methylsulfonyl and ethylsulfonyl;

C₇ -C₉ aralkylsulfonyl such as benzylsulfonyl; and

arylsulfonyl (usually C₆ -C₈) such as phenylsulfonyl and p-tolylsulfonyl.

Z¹ e preferably includes the following groups:

C₁ -C₄ alkylthio such as methylthio and ethylthio;

C₇ -C₉ aralkylthio such as benzylthio; and

arylthio (usually C₆ -C₈) such as phenylthio and p-tolylthio.

Examples of oxidants which may be used in the above oxidation reaction are peracids, sodium hypochloride, chlorine, potassium permanganate, and sodium tungstate.

Peracids are preferably selected from peracetic acid, perbenzoic acid, m-chloroperbenzoic acid, and perphthalic acid.

Peracetic acid may optionally be in situ produced in a reaction vessel by adding hydrogen peroxide to an acetic acid solution of the compound (IV-e).

Solvents which may be used in the oxidation reaction are halogenated alkyls (e.g., dichloromethane and chloroform), esters, aromatic hydrocarbons, lower fatty acids and water. Depending on the oxidants (e.g., chlorine), water should be used as solvent.

This oxidation reaction may be conducted at a temperature from under ice to the reflux point of the solvent (when a solvent is used).

Compounds (III-e) may be produced by oxidizing sulfur of commercially available reagents such as 4,6-dichloro-2-(methylthio)pyrimidine. They may also be produced by oxidizing sulfur contained in methylthio of 2-(methylthio)pyrimidine derivatives which can be prepared according to the process described in J. Chem. Soc., 1957, 1830 or in Grand Organic Chemistry, vol.17, p.94 (1959, published by Asakura Shoten).

Among substituted pyrimidine derivatives of the formula (III-e), examples of those in which Ze represents methylsulfonyl are shown in Table 3. These compounds may be used as starting materials for the production of the compounds (I) shown in Table 1 (1/15 to 15/15). In Table 3, R¹ and R² are identified by the same abbreviations as used in Table 1 (1/15 to 15/15).

Compounds of the formula (III) including Compounds III-1 to III-120 of Table 3 each may be produced as follows.

In chloroform, to each 1 mol of Compounds IV-1 to IV-120 of Table 4 below, about twice molar amount of m-chloroperbenzoic acid is added and then stirred for a period of from 1 hour to one night at room temperature. The reaction mixture is partitioned by using saturated aqueous sodium hydrogen carbonate. An organic phase is washed with saturated aqueous sodium chloride and then dried over anhydrous sodium sulfate. Thereafter, the solvent is distilled off to afford a crude product, which is then purified on column chromatography to obtain the compound of the formula (III) (Compounds III-1 to III-120).

Alternatively, Compound III-1 to III-120 may be produced through oxidation by adding hydrogen peroxide to an acetic acid solution of Compounds IV-1 to IV-120 while producing in situ peracetic acid in a reaction vessel. In this case, the reaction may be performed at a temperature in the range of from room temperature to 100° C. for a period of from 2 hours to one night.

Other compounds of the formula (III) can be obtained in a similar manner.

Among the above 2-(alkylthio, aralkylthio, or arylthio)pyrimidine derivatives, 2-(alkylthio or aralkylthio)pyrimidine derivatives can be synthesized by using the following processes.

Process (a): A compound having a 1,3-dicarbonyl group is cyclo-condensed with S-alkyl(or aralkyl)isothiourea.

This process (a) is suitable for the synthesis of the compounds in which a hydroxyl group is bonded to the positions 4 and/or 6 of 2-(alkylthio or aralkylthio)pyrimidine derivatives.

Process (b): A compound having a 1,3-dicarbonyl group is cyclo-condensed with thiourea to afford a 2-mercaptopyrimidine derivative, which is then alkylated or aralkylated at the 2-mercapto group thereof.

This process (b) is suitable for the synthesis of the compounds in which substituents are bonded to the positions 4 and 6 of the pyrimidine ring by a carbon-carbon bond, the compounds in which a hydrogen atom is bonded to either one of the positions 4 and 6 of the pyrimidine ring and a substituent is bonded to the other position by a carbon-carbon bond as well as the compounds in which a hydrogen atom is bonded to each of the positions 4 and 6 of the pyrimidine ring.

Compounds in which a halogen atom is bonded to the positions 4 and/or 6 of the pyrimidine ring can be derived from the compounds obtained by the process (a) or (b) as follows:

Process (c1), process (c2): A hydroxyl group is converted to a halogen atom by using phosphorus oxychloride (identical with phosphoryl chloride), phosphorus pentachloride, phosphorus oxybromide (identical with phosphoryl bromide or phosphoryl tribromide).

For convenience of explanation, dihalogenation and monohalogenation are designated as (c1) and (c2), respectively.

Further, a chlorine atom at the position 4 or 6 may be converted to an iodine atom through nucleophilic displacement by using potassium iodide or concentrated aqueous hydroiodic acid. Compounds in which a halogen atom and a hydroxyl group is bonded thereto can be synthesized as follows:

Process (d): Either one of the halogen atoms at the positions 4 and 6 obtained by (c1) or (c2) is converted to a hydroxyl group.

Compounds in which a substituent is ether-linked to the position 4 and/or 6 of the pyrimidine ring can be synthesized as follows:

Process (e): An oxygen atom of the hydroxyl group at the position 4 or 6 of the pyrimidine ring of the compound which was obtained from (a) or (b) is etherified in the presence of a basic compound.

Process (f): A halogen atom at the position 4 or 6 of the pyrimidine ring of the compound which was obtained from (c1) or (c2) is etherified through nucleophilic displacement in the presence of a basic compound.

Among the compounds in which a substituent is ether-linked to each of the positions 4 and 6 of the pyrimidine ring, those in which the substituent of the position 4 is different from that of the position 6 can be synthesized as follows:

Process (g): A halogen atom at the position 4 (or the position 6) of the compound obtained by (c1) is etherified through nucleophilic displacement, and then, a halogen atom at the position 6 (or 4) is etherified through nucleophilic displacement.

Process (h): A hydroxyl group of the compound obtained by (d) is etherified, and then, a halogen atom at the position 4 (or 6) is etherified.

Compounds having both an ether-linked substituent and a halogen atom, besides the above described process (f), can be synthesized as follows:

Process (i): A halogen atom at the position 4 (or 6) of the compounds obtained by (c1) is converted to a hydroxyl group, which is then etherified.

Compounds having both an ether-linked substituent and a hydroxyl group can be synthesized as follows:

Process (j): An oxygen atom of the hydroxyl group at either position 4 or position 6 of the pyrimidine ring of the compounds obtained by the process (a) or (b) is etherified in the presence of a basic compound.

Process (k): A halogen atom at the position 4 (or 6) of the compounds obtained by the process (c1) is converted to a hydroxyl group, an oxygen atom of which is then etherified. Then, a halogen atom at the position 6 (or 4) is converted to a hydroxyl group.

Examples compounds (IV-e) usable as starting materials for the production of compounds shown in Table 3 are listed in Table 4.

R¹ and R² in Table 4 are represented in a similar manner as in Table 1 (1/15 to 15/15). In the column of "Z¹ e", SMe represents methylthio.

In the column of "process" in Table 4, symbols a, b, c1, c2, e, f and g corresponds to the processes (a), (b), (c1), (c2), (e), (f) and (g) above, respectively.

Compounds represented in Table 4 can be synthesized as follows:

Each of Compounds IV-121 to IV-127 can be synthesized by using the process (a) in a manner as described in either (1) or (2) below.

(1) 0.1 mol of methyl trifluoroacetoacetate or methyl acetoacetate, about 0.05 mol of methylisothiourea sulfate (2-methyl-2-thiopseudourea sulfate) (i.e., about 1 chemical equivalent of methylisothiourea) and 0.1 mol of sodium methoxide are reacted in 500 ml of methyl alcohol at a temperature of from room temperature to a reflux point for a period of from 4 hours to one night. Then, the reaction mixture is cooled with iced water and 0.1 mol of hydrochloric acid is added thereto. After insoluble matter is filtered off, the solvent is distilled off from the filtrate to afford a crude product, which is then recrystallized to obtain a purified product.

(2) 0.1 mol of ethyl trifluoroacetacetate, ethyl propionylacetate, ethyl acetoacetate, diethyl malonate, ethyl benzoylacetate, ethyl butyrylacetate, or ethyl isobutyrylacetate, about 0.05 mol of methylisothiourea sulfate (2-methyl-2-thiopseudourea sulfate) (i.e., about 1 chemical equivalent of methylisothiourea), and 0.1 mol of sodium ethoxide are reacted in 500 ml of ethyl alcohol at a temperature of from room temperature to a reflux point for a period of from 4 hours to one night. The reaction mixture is allowed to cool to room temperature, and then, while further cooling with iced water, 0.1 mol of hydrochloric acid is added thereto. After insoluble matter is filtered off, the solvent is distilled off from the filtrate to afford a crude product, which is then recrystallized to obtain a purified product.

Each of Compounds IV-1 and IV-2 can be synthesized by the process (b).

0.1 mol of acetylacetone or acetylacetaldehyde dimethylacetal is reacted with 0.1 mol of thiourea in 300 ml of ethyl alcohol containing 10 ml of 35% hydrochloric acid for 5 hours at room temperature. The reaction mixture is allowed to cool to room temperature, and then, while further water-cooling, sodium hydrogen carbonate is added thereto. After stirring for 2 hours, insoluble matter is filtered off. Additional sodium hydrogen carbonate is added to the filtrate, and then, while stirring at room temperature, 0.1 mol of dimethyl sulfate is added and the mixture is stirred for another 3 hours. The solvent is distilled off from the reaction mixture, and thereafter, the residue is redissolved in chloroform and washed with water. After dried over sodium sulfate, the solvent is distilled off to afford a crude product, which is then purified on column chromatography to obtain a purified product.

Each of Compounds IV-3 and IV-5 can be synthesized by the process (c1).

To 1 mol of 4,6-dihydroxy-2-methylthiopyrimidine (Compound IV-124), about 2 to 3 mol of phosphorus oxychloride (identical with phosphoryl chloride) or phosphorus oxybromide (identical with phosphoryl bromide) is added to react at a temperature of 70° C. to 100° C. for a period of about 0.5 hours to about 2 hours while stirring. The reaction mixture is post-treated by using ethyl acetate and water. Ethyl acetate layer is washed successively with aqueous sodium hydrogen carbonate and water, and then, dried over sodium sulfate. The solvent is distilled off to afford an end product, which may be purified on column chromatography as desired.

Each of Compounds IV-4 and IV-6 to IV-10 can be synthesized by the process (c2).

These compounds can be synthesized by using a similar reaction procedure for the synthesis of Compound IV-5, starting from each of Compounds IV-121 to IV-123 and Compounds IV-125 to IV-127 and phosphorus oxychloride employed at a molar ratio of about 1:1 to 1:2. The obtained product may be purified on column chromatography as desired.

Compound IV-11 can be synthesized by the process (e).

0.1 mol of Compound IV-124, 100 ml of dioxane, 20 ml of 40% aqueous sodium hydroxide, and 15 ml of water are stirred at a temperature of 60° C. to 70° C. 0.65 mol of chlorodifluoromethane and 80 ml of aqueous 40% sodium hydroxide are added thereto over a period of 4 hours. At 30 minutes after addition, 30% sulfuric acid is added to adjust pH to about 6. Precipitate is filtered off from the reaction mixture, an organic phase is separated from the filtrate, an aqueous phase is extracted with 75 ml of dioxane to separate another organic phase, which is combined with the previously obtained organic phase. To the combined organic phase, 20 ml of 40% aqueous sodium hydroxide is added, and then, 0.15 mol of chlorodifluoromethane is added thereto over a period of 1 hour at a temperature of 60° C. to 70° C. Precipitate is filtered off from the reaction mixture, an organic phase is separated from the filtrate and the obtained organic phase is washed with 20 ml of 50° C. warm water. Dioxane is distilled off from the organic phase and the residue is distilled under reduced pressure to obtain a purified product.

Each of Compounds IV-12 to IV-17 can be synthesized by the process (f).

Substantially equal molar amounts of Compound IV-4 and sodium hydride are mixed with an excessive amount of 2-methyl-2-propen-1-ol (identical with methallyl alcohol), propargyl alcohol (identical with 2-propyn-1-ol), 3-methyl-3-buten-1-ol, 3-methyl-2-buten-1-ol, allyl alcohol or crotyl alcohol serving also as solvent while removing heat as desired, and stirred for 1 hour at room temperature. The reaction mixture is post-treated by using ethyl acetate and saturated aqueous sodium hydrogen carbonate solution. Organic phase is washed with saturated aqueous sodium chloride and then dried over anhydrous sodium sulfate. Organic solvent is distilled off to obtain an end product, which can then be purified on column chromatography as desired.

Compounds IV-31 to IV-36 can be synthesized by a similar reaction procedure as above, starting from Compound IV-6 in place of Compound IV-4.

Compounds IV-57 to IV-62 can be synthesized by a similar reaction procedure as above, starting from Compound IV-9 in place of Compound IV-4.

Compounds IV-63 to IV-68 can be synthesized by a similar reaction procedure as above, starting from Compound IV-10 in place of Compound IV-4.

Each of Compounds IV-18 to IV-30 can be synthesized by the process (f).

In dimethylformamide or tetrahydrofuran, Compound IV-5 and any one of 2-methyl-1-propanol, butanol, 2-methyl-2-propen-1-ol (identical with methallyl alcohol), 2,2,3,3,3-pentafluoro-1-propanol, propargyl alcohol (identical with 2-propyn-1-ol), 3,3,3-trifuoroethanol, 3-methyl-3-buten-1-ol, 3-methyl-2-buten-1-ol, allyl alcohol, crotyl alcohol, ethanol, methanol and propanol are mixed at a molar ratio of about 1:1 and stirred while cooling with iced water.

Test Example 1 (Weed control test by foliage treatment)

Wettable powders were formulated as described in Formulation example 1 and diluted to a predetermined concentration. Each of the formulated test compound was applied at a rate of 500 g/10 a onto the foliage of each plant grown to the 1 to 2 leaf stage. The tested plants were pot-cultured redroot pigweed (Amaranthus retroflexus, AR), wild mustard (Sinapis arvensis, SA), sicklepod (Cassia obtusifolia, CO), black nightshade (Solanum nigrum, SN), velvetleaf (Abutilon theophrasti, AT), cleavers (Galium aparine, GA) and ivyleafspeedwell (Veronica hederaefolia, VH).

On the 14th day after the application, weed control effects were evaluated by the following criterion. Evaluation rating:

1: less than 30%

2: 30% to less than 70%

3: 70% or more

The results are shown in Table 6.

Test Example 2 (Germination test)

In a 9 cm diameter Petri dish having the bottom covered with double sheets of filter paper, 6 ml of aqueous suspension of a test compound (containing 50 ppm of active ingredient) was poured and ten seeds of each weed were placed. The tested weeds were redroot pigweed (Amaranthus retroflexus, AR), black nightshade (Solanum nigrum, SN), wild chamomile (Matricaria chamomilla, MC), green foxtail (Setaria viridis, SV) and rice flatsedge (Cyperus iria, CI).

The seeds was allowed to germinate in a greenhouse at 28° C., and on the 14th day after the sowing, the inhibition of germination and the retarding of growth were visually observed and evaluated by the following 3-grade criterion. Evaluation rating:

1: less than 30%

2: 30% to less than 70%

3: 70% or more

The results are shown in Table 7.
